To all whmn it may concern.-

Be it known that we, WILLIAM ALFRED PHIL- Lirs and FREDERICK HU'roHIxs, electrical engineers, subjects of the King of Great Britain, residing at 185 Oxford street, London, England, haveinvented certain new and useful Improvements in Apparatus for Spinning Cotton or other Fibers, of which the following is a specification.

The invention relates to the spinning of cotton or other fiber or of cotton and other fibers in admixture.

The fiber to be spun is supplied or fed in an essentially untwisted or unspun state to a tubular channel, where it is brought within the influence of an exhaust or induced current of air, by which the fibers are conveyed to and around the spinning-point. This spinningpoint is adjacent to a central hole in a rapidlyrotating surface of wire-gauze 'or other reticulate material covering a revolving chamber in which a partial vacuum is created by a centrifugal air-wheel or by other suitable means of exhaust, which may be common to a number of spinning means. The first aggregation of the fibers rapidly floating around the central hole is brought into a spun line by means of a leading-thread center or core caused to be drawn through such central opening and then the fibers in succession become spun into a yarn or thread, and as this is drawn away the current of air supplies and spins fresh fibers robbed from the roving to continue the thread.

In carrying out our invention we have constructed an apparatus such as is shown in the accompanying drawings, wherein- Figure 1 is a vertical elevation of the spindle bearing and cover. Fig. 2 is a plan thereof. Fig. 3 is a vertical section drawn through the line E F in Fig. 4, which figure is a horizontal section taken through the line C D in Fig. 1. Figs. 5 and 6 are respectively an elevation and a plan of the spindle. Fig. 7 is a vertical elevation drawn through the line A B in Fig. 8, which latter figure is a front elevation. Fig. 9 is a vertical sectional diagram through the spindle-cover, the spindle being shown in elevation. Fig; 10 is a horizontal sectional diagram through the line G H in Fig. 9 except that the spindle is shown in plan and not in section. Fig. 11 is adiagrammatic perspective view of the spindle-head, showing the gauze top. Figs. 12 and 13 are sectional diagrams of the parts adjacent to the point where the spinning occurs.

These diagrammatic figures are intended to make clearer the path taken by the stream of fibers, as shown by the dotted line. The path taken by the air is practically the same as that taken by the fibers, except that some of the air passes through the holes 35 in the outer ring of the spindle on its way to the gauze, (as indicated by the arrow in Fig. 9.) Owing to the speed of relative rotation of ring and fibers, none of the fibers, however, pass through these holes in the outer ring. As a result of the air passing through these holes, the fibers of cotton or other material in use are attracted to the surface of the outer ring and the edges of the holes tend to separate any fibers which might otherwise cling together. The spindle rotates at an enormously rapid speed, and the edges of the holes have, as it were, a parallelizing loosening and beating action upon the fibers. The result of the draft of air, combined with the rotation of the spindle, is the production of a kind of vortex, which im pels the fibers toward the central hole in the gauze, as indicated by the dotted line 60. In Fig. 12 the dotted line represents a single fiber the leading end of which has just reached the point where the spinning of the fibers into a yarn takes place. The air vortex causes this fiber to be spun round, so that it is made to form itself spirally into a continuation of the yarn if the previouslyformed portion is drawn down at the same time, as shownin Fig. 13. Aconstant stream of fibers will of course give a continuous yarn, and if produced yarn is properly drawn away there will always be a little tail of fibers just above the hole in the gauze, as shown by the enlarged views, Figs. 12 and 13, and the fresh fibers are continuously building themselves up at this point, and so forming more yarn. Two sets of springs are provided, each set consisting of strips of fiat steel. The function of the springs 44:, which are fixtures at their opposite ends to a crutch 60, atfixed to the tube 42, is to support the formed yarn against the twisting action of the rotating springs et1, which springs serve to press upon and consolidate the yarn. \Vhile it is quite possible to obtain a yarn without the pressing-spring it would be very loose in condition, the power of the air vortex not being in itself sufficient to spin the fibers tightly enough round themselves so as to form a solid yarn.

The machine is for convenience of the drawings shown arranged for two spindles only. The machine has two standards a, only one of which is shown, and a supplementary standard 7).

c is the main shaft, driving the machine by means of fast and loose pulleys (Z 12.

f is a drum for driving the spindles. A worm r on the main shaft (2 drives a wormwheel 7/, spindle J, bevelwheels 7' A, the latter driving by chain 7 the sprocket-wheels m 49. The sprocket-wheel m is fixed on a spindle 0, having a worm driving a worm-wheel j). The latter is on the same spindle as the cam which operates the pin in a sliding shaft a,

which pin 1* is kept to its work in contact with v the said cam by a chain If, passing over a pulley H and drawn upon by a weight 2'. The shaft s carries guide-pulleys 71,, one for each spindle, thereby giving traverse motion.

in Fig. 8 the left-hand spindle is shown in elevation. The right-hand portion shows the gearing between the pull-off shaft 1 and the drawing-rollers. This shaft carries a roller 2, against which a bobbin is pressed by a spring 8. Between 5 and 2 is an endless band 9, passing over two loose pulleys 9 and 10, thereby driving pulley 11, and a gear-wheel fastened to that pulley in turn drives suitable gearing in connection with the drawingrollers 12. 13, 14:, 15, 16, and 17. bin of fibrous material, the roving from which passes through the rollers, as more clearly seen in Figs. 1 and 2. rollers may be of the usual kind employed in existing spinning-machines. In Fig. 7 the front top rollers are shown weighted by means of two links 19 19 with two levers .20 and a weight 21. 2). 23 are clearing-rollers. 2 1 is a box-girder extending right across the machine and carrying the spindles, The rotating spindles are carried in bearings 25, which are secured in the box-girder 24; by a washerQG and nut 27. The interior of the box 24 is connected by a pipe 28(see Fig. 8) with a vacuum-fan. (Not shown.) The spindle 32 is driven by a pulley 29 from the drum f by means of a band 30, which band passes over two loose pulleys 31. The spindle consists of a hollow tube 32, having a head provided with two concentric rings S t, the latter having a series of holes 35. the spindle-head has a ring of holes 36, so that the partial vacuum in the box Qecauses air to pass down through the holes 36 into the cir- 18 is a bob- The drawingcular channel 37 and through the ring of holes 38. The inner ring is provided with a gauze top or cover 39, having ahole in the center 4E0, which may conveniently be formed with an eyelet. Immediately below the gauze are two fiat springs 41, rotating with the spindle 32. inside the hollow spindle is a tube 42, held by the bracket 43, so as not to rotate, and provided at the top with two flat springs 44, similar to the springs 4C1. Surrounding the spindle-head is a fixed tubular casing to, as shown in Figs. 1, 3. and i, having an opening 46. The casings?) is closed at the top by a closing-piece dropped into the tube, which piece has, as shown, a flat bottom LT without a hole in the center; but this bottom plate may have a hole or may be coned or domed or be provided with a blunt projection shaped somewhat as a teat or otherwise be given a form around which the vortex may be generated and the spinning into a yarn promoted.

In operation the sliver or roving of fiber, such as cotton. is conveyed to the delivery rollers with a certain amount of draft arranged to be given to the roving in its passage between them,'if so desired, and from these delivery-rollers the end of the roving is carried past the outer wall with its pcrforations forming the exterior of the spindlehead, whose periphery is adapted to give a. certain amount of beating and separating action to aid the air-currentinduced by the vacuum in drawing the fibers away from the roving in a loose stream. This revolving head is inclosed in a casing to protect the fibers from extraneous influences and guide them into proximity to the edges of the openings in the outer wall 34, and the casing forms a channel which becoming constricted causes the flow of the air-borne fibers in a stream to the wire-gauze cover and around and down through the central opening in the rapidlyrotating head to receive a spiral twist and interlocking with the yarn in course of formation and removal through the fixed inner tube. The cover to this casing is, as stated, so shaped as to give the greatest aid possible to the rapid revolution of the fibers at the spinning-point.

The materials spun may be cotton. silk, (such as wild or waste silln) rabbits wool, or other comparatively short fibers.

Although we have particularly described the use of an induced current for the conveyance of fibers, at current of forced air or a current attained by impulsion and induction may be used.
